Hi all,
I have here an old Yamaha RX-300U "Natural Sound" stereo receiver I've grown rather partial to, and this afternoon I found it to be completely dead in all functions and display but the amplifiers are still functioning. My best guess on such short notice is that the PLL controller has died, and was wondering if anyone might know a source for this part.
It is a 42 pin DIP package and has the following markings:
YAMAHA XB919AO PLL CONTROLLER
3214 8F2I'm also investigating the power supply but would think that if that was at fault the amps wouldn't turn on. Could be a low voltage condition though I suppose.
Thanks for any help!!
